A DESCRIPTION OF THE PROBLEM :
The JFileChooser does not have a file type selection drop-down box in the GTK+ look and feel.  If a ".txt" file filter is used, for example, only that type of file be visible.  The box is available in the Metal look and feel.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Create a JFileChooser.
2) Pass a file filter to setFileFilter.
3) Open the JFileChooser.

EXPECTED VERSUS ACTUAL BEHAVIOR :
A file type drop-down box will be available.
No file type drop-down box will be available.  Only files from the filter's default file type are visible.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :

N/A

The native one doesn't offer these either.

Yes, this was intentional, in order to mimick the GTK file dialog.

I disagree with this approach.  SOME modifications may be
necessary, in order to not disable features that other
"Look&Feels" support.  All this disabling of features of the
JFileChooser is going to lead to are programmers building
their own JFileChooser clone that supports all the features
they need in ALL the look and feels they have to support.

As a result of this decision, I will make a point of
recommending against ever using the GTK+ L&F in any released
application.

Mimicking is one thing, dumming down to is another.
